The new compounds of general formula I are produced according to the process of the invention according to claim 1.

The production of the intermediate products of general formula II ##STR7## in which

R¹ means a methyl or ethyl radical,

1 means numbers 1 or 2,

K means a keto group blocked in the form of ketal or thioketal, and

Hal means a chlorine, bromine or iodine atom,

R^(4a), R^(4'a), Ya and Y^('a), with exclusion of the cyanide radical, have the same meaning as R⁴, R^(4'), Y and Y', and optionally present hydroxy, mercapto, amino, oxo and/or terminal acetylene groups are protected, which are also an object of the invention, is based on the compounds of formula IIIa described in European patent application EP-A 0281 428 ##STR8## in which

R¹ and K, which have the above-mentioned meaning, Hal' stands for a chlorine or bromine atom

or on the compounds of general formula IIIb obtainable according to the instructions likewise contained in EP-A 0283428 ##STR9## in which R^(4'a), Y'^(a), R^(4a) and Y^(a) as well ad K, 1 and R¹ have the meanings already mentioned above.

In the compounds of general formulas IIIa or IIIb, the chlorine atom in 2-position of the phenyl ring is generally to be exchanged for a bromine (or iodine) atom before the further reaction, for example, under the conditions mentioned in example 8a), b).

In the next step, a compound of general formula IIIa or IIIb is then converted to a compound of general formula II by epoxidation of the 9,11-double bond, for example, by reaction with a peracid, for example according to the instructions described in J. Org. Chem., 38, no. 12, p. 2267 (1973) or J. Org. Chem., 44, no. 8, p. 1351 (1979 . Preferably m-chloroperbenzoic acid is used as epoxidation agent.

Under protection of the functional groups optionally present in the 19-phenyl ring, the new compounds of general formula II are subjected to a cyclization.

The hydroxy, mercapto and keto protecting groups encompassed by K are groups which are easily cleavable in acid medium, such as, for example, the methoxymethyl, ethoxymethyl, tetrahydropyranyl, ethylenedioxyketal, ethylenedithioketal or 2,2-dimethyltrimethylenedioxyketal group. One (or more) hydroxy group or groups present on the 19-phenyl ring is or are protected by a group to be removed in a basic manner, for example, by a methoxy group. The latter can be cleaved off again, for example, by reaction with sodium thiophenolate. Protecting groups for amino groups and terminal acetylene groups (for example, the trimethylsilyl and tert-butyldimethylsilyl group) are also known to one skilled in the art and are cleaved according to the desired reaction sequence also according to processes known in the literature [Synthesis 1980, 627, J. Org. Chem. 46 (1986) 2280].

The conversion of II to the new 9o-hydroxy-19,11β-bridged steroids of general formula IVb ##STR10## in which R¹, K and 1 as well as R^(4'a), Y'^(a), R^(4a) and Y^(a) have the above-mentioned meaning and are also the object of the invention, takes place with an aryl anion as a reactive species, which can be formed after a halogen-metal exchange of the orthochlorine, bromine (or iodine) atom in the 19-phenyl ring of the compound of general formula II for an Me.sup.(+), MgX.sup.(+), Cu.sup.(+) or CuX.sup.(+) ion (Me.sup.(+) =alkali ion, X=Cl, Br, I).

For example, n-butyllithium (cf. example 1b), t-butyllithium or metallic lithium is used in an inert solvent such as diethyl ether to bring about the halogen-metal exchange and, after that, the cyclization to a compound of general formula IVb.

It had to be a surprise that in this case, a 6-membered ring (ring closure to the 11 C atom) and not a 5-membered ring (ring closure to the 9 C atom) is formed. In a similar case, only the formation of a 5-membered ring had been observed (cf. J. Org. Chem., 43. no. 19, p. 3800 (1978) and the Baldwin Rules in J. Chem. Soc., Chem. Commun. 734 (1976)).

The conversion of the thus obtained cyclization products in the finally desired end products of general formula I takes place analogously to the process known in the literature (for example, J. Fried, J. A. Edwards, "Organic Reactions in Steroid Chemistry," Van Nostrand Reinhold Company 1972, Vol. 1 and 2; "Terpenoids and Steroids," Specialist Periodical Report, The Chemical Society, London, Vol. 1-12)

by either first

a) the C-17 hydroxy group being oxidized and then

b) optionally a hydroxy group, exhibiting a protecting group, being liberated from this protecting group in the 19,11β-phenylene ring, a corresponding perfluoroalkylsulfonate (C₁ -C₄) optionally being produced from the hydroxy compound, the perfluoroalkylsulfonate being converted to a compound optionally either directly or by exchange of the perfluoroalkylsulfonate leaving group for a tin trialkyl group by the corresponding tin trialkyl compound, which exhibits the desired substitution pattern in the 19,11β-phenylene ring, optionally after further reactions,

or first b) and then a) being performed and then

c) ring D being functionalized in a desired way according to methods known in the art, the thus obtained product from the action of a dehydrating agent, which is also capable of releasing the 3-oxo group, being subjected to dehydration with the simultaneous formation of the 4(5)-double bond, and optionally the release of the 3-oxo group and the dehydration taking place in succession, and then, optionally after renewed protection of intermediately released functional groups contained in the 19,11β-phenylene ring and/or Z, the desired functions of rings A and B of the steroid skeleton being introduced or

d) the thus obtained product of the action of a dehydrating agent, which is also capable of releasing the 3-oxo group, being subjected to the dehydration with the simultaneous formation of the 4(5)-double bond, the desired functions of rings A and B of the steroid skeleton being introduced and then, after protection of the 3-oxo group, ring D being functionalized in the desired way,

or steps a) and b) being performed after step c) or d),

the thus obtained product optionally being liberated from the protecting groups, the hydroxy, mercapto and/or amino group or groups optionally contained in the 19,11β-phenylene ring optionally being alkylated or acylated, a cyanide radical optionally being introduced in the aryl substituent or substituents, the amino and/or sulfide group or groups optionally contained in the aryl substituent or substituents optionally being oxidized, optionally being reacted with hydroxylaminehydrochloride to the product of general formula I with X meaning hydroxyimino grouping N˜OH as well as a pharmaceutically compatible acid addition salt optionally being produced.

In the course of these reaction paths, it can become necessary to introduce intermediately again protecting groups in intermediate products, for example, for functional groups, contained in Z, in subsequent functionalization of rings A and B or for the 3-keto group in subsequent build-up of ring D.

The oxidation of the 17β-hydroxy group necessary for the production of almost all end products is performed in a way known in the art, for example, by Oppenauer oxidation or with chromic acid reagents (Jones' reagent or chromic acid pyridine).

The release of the 3-keto function with simultaneous dehydration and formation of the 4(5)-double bond takes place by treatment with acid or an acid ion exchanger. The acid treatment takes place in a way known in the art, by the corresponding 5α-hydroxy-3-ketal being dissolved in a water-miscible solvent, such as, aqueous methanol, ethanol or acetone, and catalytic amounts of mineral acid or sulfonic acid, such as, hydrochloric acid, sulfuric acid, phosphoric acid, perchloric acid or p-toluenesulfonic acid, or an organic acid, such as acetic acid, being allowed to act on the solution until existing protecting groups are removed and water optionally is separated. The reaction, which occurs at temperatures of 0° to 100° C., can also be performed with an acid ion exchanger. The course of the reaction can be followed with analytical methods, for example, by thin-layer chromatography of gathered samples.

In general, the removal of the protecting groups and dehydration is achieved in one reaction step by the corresponding 5α-hydroxy-3-ketal or 5-ene-3-ketal being allowed to react in a strongly acidic medium for a certain period, as is described in example 1i). But just as it is possible according to the invention to perform the removal of the protecting groups and dehydration in two reaction steps separated from one another, first by the corresponding 5α-hydroxy-3-keto compound being obtained first by a shorter treatment of the corresponding 5α-hydroxy-3-ketal in moderately acidic medium and optionally at a temperature of 0° C. or below and optionally being isolated, as is shown by way of example in example 8. The 5α-hydroxy-3-keto compound is then converted to the 3-keto-4-ene compound by further allowing acid to act under dehydration.

The selective removal of the protecting group without dehydration is possible in some cases also in strongly acidic medium (e.g., 4 n HC1), if it is allowed to react only for a short time at 0° C. or below.

A quite special advantage of this invention lies in the large bandwidth of the substituents introducible at the 19-phenyl radical (M. Pereyre, J.-P. Quintard, A. Rahm, Tin in Organic Synthesis: Butterworths, 1987). For one thing, substituents R⁴ --Y-- or R^(4') --Y'-- present in the later end product can be introduced directly by a compound of general formula IIIb (cf. EP-A 0283 428).

With another embodiment of the process according to the invention, it is possible to vary the substituent or substituents in the 19,11β-phenylene radical over a wide range, by the substituent or substituents first being introduced after the cyclization, namely before, simultaneously with or only after the finishing of the structure of rings A, B and D. For this purpose, at least one of the hydroxy groups present and protected in the 19,11β-phenylene radical in formula IVb is liberated from its protecting group and the corresponding perfluoroalkylsulfonate compound is produced from the free OH compound by reaction with perfluoroalkylsulfonic acid anhydride (alkyl=C₁ -C₄) according to methods known in the art (P. J. Stang, M. Hanack and L. R. Subramanian, Synthesis 85 (1982)].

In this case, either the perfluorosulfonate leaving group is displaced with basically almost simultaneous substitution by the desired substituent or its precursor in a reaction catalyzed by transition metal (preferably Pd^(o)) (J. E. McMurry and S. Mohanraj, Tetrahedron Letters, 24, no. 27, pp. 2723-2726, 1983; X. Lu and J. Zhu, Communications, pp. 726-727, 1987; Q.-Y. Chen and Z.-Y. Yang, Tetrahedron Letters 27, no. 10, pp. 1171-1174, 1986; S. Cacchi, P. G. Ciattini, E. Morera and G. Ortar, Tetrahedron Letters, 27, no. 33, pp. 3931-3934, 1986; A. M. Echavarren and J. K. Stille, J. Am. Chem. Soc. 1987, 109, pp. 5478-5486) or a corresponding triorganylstannyl, preferably a tri-n-alkylstannyl compound, intermediately and catalyzed by transition metal, is produced from the perfluoroalkylsulfonate compound [J. K. Stille, Angew. Chem. [Applied Chem.] 98 (1986), pp. 504-519]. The latter is then reacted with a halogen-, preferably bromine- or iodine-substituted carbocyclic (cf. example 6c) or heterocyclic aromatic substance (cf. example 3b) [Y. Yamamoto, Y. Azuma, H. Mitoh, Communications, pp. 564-565, 1986; T. J. Bailey, Tetrahedron Letters, 27. no. 37, pp. 4407-4410, 1986], which optionally can have even further substituents; the 19,11β-phenylene radical then exhibits in it the desired substitution or a precursor of the desired substitution. The precursors are further processed to the finally desired compounds according to standard methods of organic chemistry.

If the 19-phenyl ring exhibits two protected hydroxy groups, to start with only the protecting group of one (the first) hydroxy group can be selectively removed, the free hydroxy group can be functionalized, then optionally the protecting group of the second hydroxy group can be cleaved off and this hydroxy group can be modified, optionally also by reaction with the function now found on the first hydroxy group.

The introduction of 1,2 and/or 6,7-double bonds besides the 3,4-double bond is possible according to known methods, for example, with dehydrating agents, such as seleniumdioxide, chloranil, thallium triacetate or dichlorodicyanobenzoquinone (DDQ).or by allyl or dienol ether bromation and subsequent hydrobromic acid cleavage [J. Fried, J. A. Edwards, Organic Reactions in Steroid Chemistry, Van Nostrand Reinhold Company 1972, pp. 265-374, 1; Tetrahedron 42, (1986) 2971].

The allyl bromation is performed in a solvent, for example, with N-bromosuccinimide, N-bromoacetamide, 1,3-dibromo-5,5-dimethylhydantoin or dibromotetrachloroethane in the presence of a radical former such as dibenzoyl peroxide. As solvent, aprotic solvents such as dioxane and chlorinated hydrocarbons, such as, for example, carbon tetrachloride, chloroform or tetrachloroethylene are suitable. The reaction takes place between 0° C. and the boiling temperature of the solution.

The dienol ether bromation is performed, for example, analogously to the instructions in Steroids I, 233.

The hydrobromic acid cleavage with formation of the Δ⁶ -double bond takes place by heating the 6-bromine compound with basic agents, preferably with lithium bromide and lithium carbonate or with lithium bromide and calcium carbonate in an aprotic solvent, such as dimethylformamide, at temperatures of 50° to 120° C. Another possibility of the HBr cleavage consists in that the 6-bromine compound is heated in collidine or lutidine.

Starting from a saturated ring A, double bonds can be introduced simultaneously in 1,2- and 4,5-position, for example, by bromation to 2,4-dibromo-3-ketone and dehydrobromation of the dibromide with, for example, lithium or calcium carbonate and lithium bromide in dimethylformamide.

The introduction of a 6-methylene group can take place, for example, starting from a 3-amino-3(4),5(6)-diene derivative by reaction with formalin in alcoholic solution (Helv. Chim. Acta. 56 (1973) 2396) to the 6o-hydroxymethyl group and then acidic dehydration, for example, with hydrochloric acid in dioxane/water or starting from a 3-alkoxy-3(4),5(6)-diene derivative, analogously to the method described in U.S. Pat. No. 4,544,555 or directly, starting from a 3-oxo-4(5)-ene derivative analogously to the instructions in Synthesis (1982) 34.

The methylenation of the 6-methylene compound to the 6,6-ethylene compound takes place with dimethylsulfoxonium methylide. For this purpose, the 6-methylene steroid is added to a suspension of trimethylsulfoxonium iodide with sodium hydride in mineral oil and dimethylsulfoxide or to a solution of trimethylsulfoxonium iodide and sodium hydroxide in dimethyl sulfoxide. The reaction is completed after 15 to 60 minutes at 20° to 40° C. (J. Am. Chem. Soc. 84 (1962) 866; European patent application 0150157). The introduction of a 2-methylene group takes place analogously to the method of A. J. Manson and D. Wood [J. Org. Chem. 32 (1967) 3434] or the methods cited there.

The methylenation of the 2-methylene compound to the 2,2-ethylene compound takes place analogously to the methylenation of the 6-methylene compound [also see Chem. Ber. 98 (1965) 1470].

Monoalkylated or dialkylated compounds in 2-position can be obtained, for example, analogously to the method of L. Nedelec, Tetrahedron 30 (1974) 3263.

Alkylated compounds in 1- or 7-position are obtained by 1,4- or 1,6-addition to the corresponding enones according to known methods (J. Fried, J. A. Edwards: Organic Reactions in Steroid Chemistry, Van Nostrand Reinhold Company 1972, pages 75 to 82, 2; and J. Am. Chem. Soc. 99 1977) 1673).

Alkylated compounds in 6-position can be obtained, for example, by opening the corresponding 5α,6α-epoxides and secondary reactions (J. Fried, J. A. Edwards: Organic Reactions in Steroid Chemistry, Van Nostrand Reinhold Company 1972, pages 82-86, 2).

1α-, 2α-, 6α-, 7α-, 6β-, 7β-methylene compounds or a combination of the 1α,2α-methylene structural element with both 6,7-methylene structural elements allow the corresponding allyl alcohols to be obtained by adding diazomethane or dimethylsulfoxonium methylide to the corresponding enones or by a Simmons-Smith reaction (J. Fried, J. A. Edwards: Reactions in Steroid Chemistry, Van Nostrand Reinold Company 1972, pages 100-126; Rev. Soc. Quim. Mex. (1969) 171A; Chem. Ber. 101 (1968) 935; Chem. Ber. 99 (1966) 1118; Zeitschr. f. Naturf., 19b (1964) 944).

The production of the isoxazole ring annelated on 2- and 3- positions takes place by the synthesis of the 2-hydroxymethylene compounds [Steroids 6 (1962) 178; J. Amer. Chem. Soc. 83 (1961) 1478]and their reaction with hydroxylamine [J. Med. Chem. 6 (1963) 1].

[2,3-d]Isoxazoles are also good initial materials for the synthesis of 2-cyano steroids [J. Med. Chem. 6 (1963) 1].

The production of the pyrazole ring annelated in 2- and 3-positions takes place by reaction of 2-hydroxymethylene-3-oxo feedstocks with R¹¹ -substituted hydrazine (US patent 3,704,295).

The introduction of chlorine or methyl substituents in C-6 of the steroid skeleton is possible, e.g., by the methods indicated in German laid-open specification 1,158,966 or in U.S. Pat. No. 4,544,555 and U.S. Pat. No. 4,196,203 by the corresponding 6,7-epoxides or 6-methylene derivatives as well as by oxidation of the 6-chloro-3,5-dienol ether with dichlorodicyanobenzoquinone (DDQ) under acidic conditions [Belgian patent 621,197 (1962)].

The removal of the 3-oxo group for an end product of general formula I with X meaning two hydrogen atoms can take place, e.g., according to the instructions indicated in DOS 2805490 by thioketalization and subsequent reductive cleavage.

Feedstocks with a D-homo-steroid skeleton are also to be obtained, e.g., by Tiffeneau rearrangement analogously to the instructions published in Australian J. Chem. 8 (1955), 519 and in "Organic Reactions in Steroid Chemistry" Vol. 2, 388. The necessary 17α-aminomethyl-17β-hydroxy compounds are accessible, for example, by the opening of the 17,20-spiroepoxides with ammonia or also by lithium aluminum reduction of the acetylated 17β-hydroxy-17α-cyano compounds. The spiroepoxides are accessible by conversion of the corresponding 17-ketones with dimethylsulfonium methylide to dimethylformamide [Journal f. prakt. Chemie 314 (1972), 667-668). The acetylated cyanohydrines are accessible by adding cyanohydrogen to the corresponding 17-ketones and subsequent acetylation according to known instructions (e.g., Australian J. Chem. 8 (1955), 519).

Feedstocks with an unsaturated D-ring are accessible, for example, by modified Saegusa oxidation (Tetrahedron 42 (1986) 2971) of the corresponding enol compounds of the 17-ketone. For example, the trimethylsilylenol ether can be produced by converting the 17-ketone with lithium diisopropylamide in tetrahydrofuran to the corresponding enolate and trapping by trimethylchlorosilane (Synthesis 1983. 1).

The introduction of substituents R⁵ and R⁶ takes place according to the usual process of the C-17 side chain synthesis by nucleophilic addition to the 17-ketone--obtained by, e.g., Oppenauer oxidation of the C-17 hydroxy group--and secondary reactions ("Terpenoids and Steroids," Specialist Periodical Report, The Chemical Society, London, Vol. 1-12).

The introduction of substituents --C.tbd.C--U as R⁶, and U has the above-mentioned meaning, takes place with the help of a compound of general formula MC.tbd.C--U', in which U is an alkine protecting group, such as, for example, the trimethylsilyl or tert-butyldimethylsilyl radical, or else if U is an alkyl group with 1-4 C atoms, U' itself is radical U.

The organometallic compound can also be formed in situ and brought to reaction with the 17-ketone. Thus, acetylene and an alkali metal, in particular potassium, sodium or lithium, can be allowed to act in the presence of an alcohol or in the presence of ammonia for example on the 17-ketone in a suitable solvent. The alkali metal can also take effect in the form of, for example, methyllithium or butyllithium. As solvent, in particular dialkyl ether, tetrahydrofuran, dioxane, benzene and toluene are suitable.

The introduction of 3-hydroxypropine, 3-hydroxypropene or 3-hydroxypropane in 17-position takes place by reacting 17-ketone with the dianion of propargyl alcohol (3-hydroxypropine), for example, the dipotassium salt, generated in situ, of the propargyl alcohol, to the 17α-(3-hydroxyprop-1-inyl)-17β-hydroxy derivative or with metalated derivatives of 3-hydroxypropine, for example, with 1-lithium-3-(tetrahydropyran-2'-yloxy)-prop-1-in-1-ide, to the 17-[3-(tetrahydropyran-2'-yloxy)-prop-1-inyl]-17β-hydroxy derivative, which then can be hydrogenated to the 17-(3-hydroxypropyl- or hydroxypropenyl)17β-hydroxy compounds. This is possible, for example, by hydrogenation at room temperature and standard pressure in solvents such as methanol, ethanol, propanol, tetrahydrofuran (THF) or ethyl acetate by adding noble metal catalysts such as platinum or palladium.

The introduction of homologous hydroxyalkine, hydroxyalkene and hydroxyalkane groups takes place in a corresponding way with homologues of propargyl alcohol.

The compound with the Z-configured double bond in the hydroxypropenyl group results by hydrogenation of the acetylenic triple bond with a deactivated noble metal catalyst (J. Fried, J. A. Edwards: Organic Reactions in Steroid Chemistry, Van Nostrand Reinhold Company 1972, page 134; and H. O. House: Modern Synthetic Reactions 1972, page 19). As deactivated noble metal catalysts, for example, 10% palladium on barium sulfate in the presence of an amine or 5% palladium on calcium carbonate with adding lead(II) acetate is suitable. The hydrogenation is broken off after the absorption of one equivalent of hydrogen.

The compound with the E-configured double bond in the hydroxypropenyl group results by reduction of the acetylenic triple bond in a way known in the art. In the literature, an entire series of methods to convert alkines into trans-olefins is described, for example, the reduction with sodium in liquid ammonia (J. Am. Chem. Soc. 63 (1941) 216), with sodium amide in liquid ammonia (J. Chem. Soc. 1955, 3558), with lithium in low-molecular amines (J. A. Chem. Soc. 77 (1955) 3378), with boranes (J. Am. Chem. Soc. 93 (1971) 3395 and 94 (1972) 6560), with diisobutylaluminum hydride and methyllithium (J. Am. Chem. Soc. 89 (1967) 5085) and in particular with lithiumaluminum hydride/alcoholate (J. Am. Chem. Soc. 89 (1967) 4245). Another possibility is the reduction of the triple bond with chromium(II) sulfate in the presence of water or dimethylformamide in weakly acidic medium (J. Am. Chem. Soc. 86 (1964) 4358) as well as generally the reduction by the action of transition metal compounds with alternation of the oxidation stage.

The introduction of the hydroxyalkenes can also take place directly by adding a corresponding metalated hydroxyalkenyl compound, such as, for example, 1-lithium-3-(tetrahydropyran-2'-yloxy)-prop-1(E)-ene (J. Org. Chem. 40 2265) or 1-lithium-3-(tetrahydropyran-2'-yloxy)-prop-1(2)-ene (Synthesis 1981, 999). Homologues can also be introduced in this way.

The introduction of 3-hydroxypropane in 17-position can also take place directly by reaction of the 17-ketone with metalated derivatives of 3-halopropanols--and the hydroxy group in the metalation step is present as alcoholate (Tetrahedron Letters 1978, 3013) or as a protected function (J. Org. Chem. 37, 1947) --to the 17-(3-hydroxypropyl)-17β-hydroxy compound or to the compound protected on the terminal hydroxy group. As protecting groups, for example, the ethoxyethyl, tetrahydropyranyl and methoxymethyl groups are suitable.

If end products of formula I are desired with R⁵ /R⁶ meaning ##STR11## the 17-(3-hydroxypropyl) compound is oxidized in a way known in the art, for example, with Jones' reagent, manganese dioxide, pyridinium dichromate, pyridinium chlorochromate, chromic acid pyridine or the Fetizon reagent silver carbonate/Celite (Compt. rend. 267 [1968] 900).

The production of end products of formula I with R⁵ /R⁶ meaning ##STR12## takes place by ring closure reaction of the corresponding 17-(3-hydroxyprop-1-(Z)-enyl-17β-hydroxy feedstock.

If R⁵ /R⁶ together stand for ##STR13## either an above-described dihydrofuran compound is catalytically hydrogenated or the corresponding 17-(3-hydroxypropyl)-17β-hydroxy compound is cyclized.

The synthesis of the 17-cyanomethyl side chain takes place in a way known in the art from the 17-ketone, for example, by the 17-spiroepoxide and cleavage of the spiroepoxide with HCN according to Z. Chem. 18 (1978) 259-260.

Also, the introduction of the 17-hydroxyacetyl side chain takes place according to methods known in the art, for example, according to the methods described in J. Org. Chem. 47 (1982), 2993-2995, Chem. Ber. 113 (1984), 1184 or U.S. Pat. No. 4,600,538.

To introduce the groupings ##STR14## 17-ketone is converted with tosylmethyl isocyanide (Chem. Ind. 1972 213) to the 17-nitrile compound (Tetrahedron 31 (1975), 2151), which can be converted directly with methyllithium or methylmagnesium bromide to the 17-acetyl compound, which yields the desired 17α-methyl-17β-acyl grouping after enolization with k-tert0butylate in tetrahydrofuran and reaction with methyl iodide. This sequence of adding methyl to the nitrile and subsequent alkylation can also be performed in reverse sequence.

Free hydroxy or hydroxy, mercapto and/or amino groups present in Z or in the 19,11β-phenylene ring can be alkylated or acylated in a way known in the art.

Sulfides and/or dialkylamines contained in the 19,11β-phenylene ring can be converted by suitable oxidizing agents (for example, hydrogen peroxide or peracids) to the desired sulfoxides (n=1), N-oxides (n=1) [see, e.g., Kontakte [Contacts] (Darmstadt) 1986, 3, p. 12] or sulfones (n=2).

Compounds with a dialkylamine substituent in the 19,11β-phenylene ring can be converted to the corresponding (N-cyano-N-alkylaminoaryl) derivatives by reaction with bromocyanogen in aprotic solvents such as, for example, dioxane, benzene or toluene at elevated temperature (amine degradation according to Braun) analogously to the instructions indicated, for example, in Org. Reactions 7, 198 (1953), K. W. Bentley, Techniques of Organic Chemistry 11, 773 (1963) and Houben-Weyl, 5/4, 151 (1960) in good yields.

The latter are reduced depending on the finally desired meaning of R¹² in the end product in a way known in the art to the corresponding dialkylamine compounds (for example, with diisobutylaluminum hydride in toluene to the N-formyl-N-alkylaminophenyl intermediate products and then with lithiumaluminum hydride) or N--H--N--alkyl compounds (for example, with lithiumaluminum hydride or with lithium in liquid ammonia). The latter are then optionally acylated in a way known in the literature and optionally then reduced in a known way with, for example, lithiumaluminum hydride to the new dialkylamine derivative (see DE 36 23 038).

The obtained compounds of general formula I with X meaning an oxygen atom can optionally be converted by reaction with hydroxylamine hydrochloride in the presence of tertiary amines at temperatures between -20° and +40° C. in the oximes (formula I with X meaning the hydroxyimino grouping N OH, and the hydroxy group can be in syn-position or anti-position). Suitable tertiary bases are, for example, trimethylamine, triethylamine, pyridine, N,N-dimethylaminopyridine, 1,5-diazabicyclo[4.3.0]nonene-5 (DBN) and 1,5-diazabicyclo[5.4.0]undecene-5 (DBU), and pyridine is preferred. The new compounds of general formula I as well as their addition salts with pharmaceutically compatible acids are valuable pharmaceutical agents. Thus, they have at their disposal a strong affinity to the gestagen receptor and have a surprisingly large range of antigestagen, antiglucocorticoidal and antimineralcorticoidal properties. These important biological activities can be used for medicinal purposes.

Active ingredients of this type with pronounced, antigestagen activity are suitable for inducing abortions, since they displace by receptor the progesterone necessary for maintaining the pregnancy. Therefore, they are valuable and advantageous in view of their use for postcoital birth control.

They can also be used for treatment of hormonal irregularities, for inducing menstruation, for inducing labor and for treating endometriosis. Further, they can be used for the treatment of hormone-dependent cancers.

To determine the antigestagen activity of the compounds of general formula I, the rat abortive test described in EP-A 0283 28, page 12, was performed as a typical example with 9α,17β-dihydroxy-17-(prop-1-inyl)-11β,19-[4-(3-pyridyl)-o-phenylene]-4-androsten-3-one:

The compounds of general formula I according to the invention as well as their addition salts with pharmaceutically compatible acids also exhibit an antiglucocorticoidal activity and can thus also be used as pharmaceutical agents for the treatment of corticoid-induced disorders (glaucoma) as well as for control of side effects, which occur with long-term treatment with glucocorticoids (Cushing Syndrome). They therefore make it possible also to control the disorders attributable to a hypersecretion of the glucocorticoids, above all obesity, arteriosclerosis, hypertension, osteoporosis, diabetes as well as insomnia.

The compounds of general formula I according to the invention as well as their addition salts with pharmaceutically compatible acids with antimineralcorticoidal properties can be used to treat disease conditions, in which a hyperaldosteronism is involved.

Thus, the invention relates also to pharmaceutical agents based on pharmaceutically compatible, i.e. nontoxic in the doses used, compounds of general formula I as well as their addition salts with pharmaceutically compatible acids, optionally together with the usual auxiliary agents and vehicles.

The compounds according to the invention and their salts can be processed according to the methods of galenicals known in the art to pharmaceutical preparations for enteral, percutaneous, parenteral or local administration. They can be administered in the form of tablets, coated tablets, gel capsules, granular powders, suppositories, implants, injectable, sterile, aqueous or oily solutions, suspensions or emulsions, ointments, creams and gels.

The active ingredient or ingredients can be mixed in this case with the auxiliary agents usual in galenicals such as, e.g., gum arabic, talc, starch, mannitol, methyl cellulose, lactose, surfactants such as Tweens® or Myrj®, magnesium stearate, aqueous or nonaqueous vehicles, paraffin derivatives, wetting agents, dispersing agents, emulsifiers, preservatives and aromatic substances for taste correction (e.g., ethereal oils).

Thus, the invention also relates to pharmaceutical compositions, which as active ingredient contain at least one compound according to the invention or one of their addition salts with pharmaceutically compatible acids.

As addition salts of the products with acids according to the invention, hydrochloride and methanesulfonate can be mentioned in particular.

A dosage unit contains about 1-100 mg of active ingredient or ingredients.

The dosage of the compounds according to the invention in humans is about 1-1000 mg per day.
